Explanation:
1) A rock is a naturally occurring solid. It is made of minerals (which are crystalline), or other mineral-like substances.
2) Igneous rocks are formed by the cooling of molten magma on the Earth's surface. The magma, which is brought to the surface through fissures or volcanic eruptions, solidifies at a faster rate. So extrusive igneous rocks are smooth, crystalline, and fine-grained.
3)Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
